  • Element Details

    • inputChannel

      String inputChannel
      Specify the channel from which this transformer will consume messages. If the channel does not exist, a DirectChannel with this name will be registered in the application context.
      Returns:
      The channel name.
      Default:
      ""

    • outputChannel

      String outputChannel
      Specify the channel to which this transformer will send the transformed message.
      Returns:
      The channel name.
      Default:
      ""

    • adviceChain

      String[] adviceChain
      Specify a "chain" of Advice objects that will "wrap" the message handler. Only the handler is advised, not the downstream flow.
      Returns:
      the advice chain.
      Default:
      {}

    • sendTimeout

      String sendTimeout
      Specify the maximum amount of time in milliseconds to wait when sending a reply Message to the outputChannel. Defaults to -1 - blocking indefinitely. It is applied only if the output channel has some 'sending' limitations, e.g. QueueChannel with fixed a 'capacity'. In this case a MessageDeliveryException is thrown. The 'sendTimeout' is ignored in case of AbstractSubscribableChannel implementations. Can be specified as 'property placeholder', e.g. ${spring.integration.sendTimeout}.
      Returns:
      The timeout for sending results to the reply target (in milliseconds)
      Default:
      ""

    • autoStartup

      String autoStartup
      The SmartLifecycle autoStartup option. Can be specified as 'property placeholder', e.g. ${foo.autoStartup}. Defaults to true.
      Returns:
      the auto startup boolean flag.
      Default:
      ""

    • phase

      String phase
      Specify a SmartLifecycle phase option. Defaults Integer.MAX_VALUE / 2 for PollingConsumer and Integer.MIN_VALUE for EventDrivenConsumer. Can be specified as 'property placeholder', e.g. ${foo.phase}.
      Returns:
      the SmartLifecycle phase.
      Default:
      ""

    • poller

      Poller[] poller
      Returns:
      the Poller options for a polled endpoint (PollerMetadata). This attribute is an array just to allow an empty default (no poller). Mutually exclusive with reactive().
      Default:
      {}

    • reactive

      Reactive reactive
      Returns:
      the Reactive marker for a consumer endpoint. Mutually exclusive with poller().
      Since:
      5.5
      Default:
      @org.springframework.integration.annotation.Reactive("\n\t\t\n\t\t\n\ue000\ue001\ue002\n\t\t\t\t\n")
